APPENDIX TO PARTS I AND II. 



upon good evidence to be i6 feet higher t^an was formerly supposed (see Vol. I, pp. 

 250-252). Referred to this datum, however, the height of Winnipiseogee lake appears 

 to be II feet above that obtained by the survey for the Portsmouth, Great Falls & Con 

 way Railroad (Vol. I, p. 265). One of these determinations of the level of the lake 

 must be incorrect. Heights along Contoocook river and on streams in Antrim, with 

 corrections to be made in Volume I, page 268, are stated in this volume on pages 102 

 and 119; heights along Salmon Falls river, on page 150; and in Dover, on page 156. 

 Mr. George L. Whitehouse, of Farmington, informs us that the height given in Volume 

 I, page 264, for the summit between Alton and Farmington, refers to the highest point 

 of the railroad, while the greatest depth that would have to be cut through to turn Win- 

 nipiseogee lake into Cochecho river is only 28 feet, which calls for a correction on page 

 129 of this volume. 



To the tables of altitudes previously published, we append a few additional observa- 

 tions, principally in the mountain region :
